Today I did couple of updates on the front-end side of things, and then I did get the execution exception error, while running the app, that points to the written code within the target folder.
Error:
Execution exception
[IllegalStateException: java.lang.reflect.InvocationTargetException]
Pinter to the error on line 31 (/target/scala2.11/routes/main/controllers/ReverseRoutes.scala:31):
28 // #LINE:65
29 def versioned(file:Asset): Call = {
30 implicit val _rrc = new ReverseRouteContext(Map(("path", "/public")))
31 Call("GET", _prefix + { _defaultPrefix } + "vassets/" + implicitly[PathBindable[Asset]].unbind("file", file))
32 }
Where should I look for this error, as obviously I did not wrote the code within the target folder.
Note 1: Commented whatever I did after I did get the error, and I do still get the error.
Note 2: I did clean compile with no error, however when I try to run it through the browser I do get the error.
this error is strictly connected with template and using controllers call (your methods from controllers)
you have to localize on your template which controller method calls this error
for instance I had a problem with nullpointerexception and I found a problem. I had below controller:
#controllers.MyController.myMethod(object.getValue)
and it turns out that in db getValue had null and play reported it as a problem. he somehow detect that this value is null
Strange for me but maybe it will help

I'm using Dexie.js version 3.0.3-rc.3 in a Vue JS project and I occasionally run into this exception in Chrome (86):
Failed to execute 'bound' on 'IDBKeyRange': The parameter is not a valid key.↵ DataError: Failed to execute 'bound' on 'IDBKeyRange': The parameter is not a valid key.
Here's a screenshot of the full error:
I'm fairly certain the problem lies with something in my data being undefined, but I'm trying to find a good way to troubleshoot this. I paused the Chrome dev tools on exceptions and inspected the code around this particular part of Dexie, but it doesn't reveal what data was used to make this exception occur.
Does anyone have any suggestions on how to find out what's actually wrong? It feels a bit like a needle in a haystack.
== Update ==
Below is the full call stack:
Try inspecting the call stack. I know it can be long until you reach a frame within your application code, but the failing call should be there!
I've run into the dreaded Reflection.emit issue in my webplayer build and am unable to locate what is triggering it. I'm currently commenting out code method by method and rebuilding to locate the cause and have narrowed it down to the below.
I'm not using JSON so the various JSON libraries aren't the cause, nor any of the other result suggestions returned by google.
How can i more easily go about locating the cause of this error. I have full stack trace on and well as full debugging, but all i get is the following console output.
NotSupportedException: C:\Program Files\Unity 2018.2.0b2\Editor\Data\il2cpp\libil2cpp\icalls\mscorlib\System.Reflection.Emit\AssemblyBuilder.cpp(20) : Unsupported internal call for IL2CPP:AssemblyBuilder::basic_init - System.Reflection.Emit is not supported.
Rethrow as TypeInitializationException: The type initializer for 'System.Reflection.Emit.DynamicMethod.AnonHostModuleHolder' threw an exception.
//NOTE: appM.procM is a C# .Net 4.x dynamic variable EG:
//public dynamic procM = GetProcClass(strProcName)
public void ShowProcList() {
/* Rest of method commented out*/
if(appM.procM == null){
procList.Initialize(appM.procM.lstNames, this);
}
/* Rest of method commented out*/
}
public void Initialize(List<string> lstNames, UIM um, string currProc=null) {
uiM = um;
//cleanup of the list before populating
foreach(Transform fld in Panel.transform) {
Destroy(fld.gameObject);
}
/* Rest of method commented out*/
}
Update: I narrowed down the problem line of code, but haven't closed the question as there's got to be an easier way than commenting out line by line and rebuilding.
For future searchers, the issue is the if(appM.procM == null) check. As procM is a dynamic variable reflection is used which kills AOT in webGL builds. No compiler warnings were generated to save myself from myself.
Nevermind, i am an idiot, The option Enable Exceptions under Player Settings was set to Full Without Stacktrace and not Full with Stacktrace.
The value Full With Stacktrace contains the pertinent data. Easily locatable in the browsers console. Warning that full debugging does increase build times and slow down the application.
The error popup with the following error message comes on the screen repeatedly when application is in idle state (no user activity is performed).
Error occurred on client: (TypeError): Unable to get property 'iterator_0' of undefined or null reference.

Can anyone give some pointers to navigate to the problamatic area in the code?
The fact that you're getting it repeatedly is probably due to the fact that you're performing an action on a timer (i.e. perform repeatedly an action).
From the small snippet you've shown, I don't think there's anything we can deduce. Do you have a larger stacktrace? It is still possible the error is in your own code (trying to invoke iterator() on a null object).
I have a strange problem with the new Xcode 8 (no beta version) and swift3.
Once every other 3-4 times that I compile my code I get a 'command failed due to signal segmentation fault 11' error. I just need to enter new empty line, or sometimes changing some spaces, or add a comment (everywhere in the code) and the error disappears and I can compile again.
This is really strange because I'm not changing anything in the code! And sometimes I can compile and it works, then I don't change anything, I compile again and I get the error.
This is really annoying!
I have noticed this is happening since I have installed several 'Firebase' pods (Firebase, Firebase/Auth etc...). But I need them.
Anyone has any suggestion?
PS: I have set the Enable Bitcode of my project to No as many solution suggested, but nothing. In the error message it is not indicated any swift page where the error can be, an example is:
While loading members for 'Class_name' at
While deserializing 'func_name' (FuncDecl #42)
'func_name' is this one:
public class func loginUser(fir_user: FIRUser) {
let user = SFUser()
user.email = fir_user.email
user.isLogged = true
try! sfRealm.write() {
sfRealm.add(user, update:true)
}
var userToAdd = [String:AnyObject]()
userToAdd["email"] = fir_user.email! as NSString
let ref=FIRDatabase.database().reference()
let usersRef = ref.child(childName)
usersRef.setValue([key:value])
}
But then, as I said, I can just enter an empty row in another file and it compiles!
Thanks
I have the same issue i just figure out that i was using xcode 8.1 and the project's working copy was in xcode 8.2.1 so i just re install xcode 8.2.1 and problem got solved. Hope other can get the help trough this.
Ok, it seems that I have found the solution: it is a problem with Firebase and cocoapods, so 2 solutions:
Download Firebase and import into your project
I, instead, updated cocoapods to the last version and it worked. Upgraded Firebase - Now Getting Swift Compile Error
In my case there was some type checking issue deep down the compiler so the editor didn't give error in the gutter but on building the project I was getting signal setmentation fault 11 error:
1. While type-checking 'GetStoreAPIRequestModel' at /Users/.../StoreAPIModel.swift:9:1
2. While type-checking expression at [/Users/.../StoreAPIModel.swift:15:18 - line:15:31] RangeText="[Dictionary]()"
3. While resolving type [Dictionary] at [/Users/.../StoreAPIModel.swift:15:18 - line:15:29] RangeText="[Dictionary]"
So I changed my code from:
var stores = [Dictionary]() {
willSet {
allStores.removeAll()
for model in newValue {
allStores.append(StoreAPIModel(dictionary: model as! Dictionary).getModel())
}
}
}
To (more descriptive dictionary):
var stores = [[String : Any]]() {
willSet {
allStores.removeAll()
for model in newValue {
allStores.append(StoreAPIModel(dictionary: model as [String : AnyObject]).getModel())
}
}
}
This is tricky problem. Issue can be with line of code or syntax. I was getting similar error and it was due to incorrect usage of dictionary. I was trying to increment the value of dictionary element.
Solution is to triage the code, detailed error provide which module has issue, so try commenting part of code until you find the line which is causing the issue.
Hi i had the same issue with FireBase , my problem was that i was extending FIRStorageReference and FIRDatabaseReference and some time it compile successfully some time i get
command failed due to signal segmentation fault 11
so i removed that files and implement the method other way , now everything works fine.
Found my problem when this occurred. (No cocoapods.) I thought I had left the program in a working state, but I was wrong. I am writing a straightforward command-line program. What it does is somewhat general, so I defined all the strings that make it specific in let statements at the top of the program so that I could someday use the program in a different context.
Since that was working so well, I thought I'd be clever and do the same with a filter of an array of dictionaries. I turned:
list.filter { $0["SearchStrings"] == nil }
into:
let test = { $0["SearchStrings"] == nil }
// ...
list.filter(test)
meaning to continue working on the let, but I never went back and did that. Building gave me the segmentation fault error. Defining test as a function fixed the problem.
(Incidentally, I understand how to strip a filtering function down to the terse braces notation in the context of the call to Array.filter, and why that works, but I don't understand why I can't assign the brace expression to a constant and use it as such.)
I have an All Exceptions breakpoint configured in Xcode:
Sometimes Xcode will stop on a line like:
[managedObjectContext save:&error];
with the following backtrace:
but the program continues on as if nothing happened if you click Continue.
How can I ignore these "normal" exceptions, but still have the debugger stop on exceptions in my own code?
(I understand that this happens because Core Data internally throws and catches exceptions, and that Xcode is simply honoring my request to pause the program whenever an exception is thrown. However, I want to ignore these so I can get back to debugging my own code!)
Moderators: this is similar to "Xcode 4 exception breakpoint filtering", but I think that question takes too long to get around to the point and doesn't have any useful answers. Can they be linked?
For Core Data exceptions, what I typically do is remove the "All Exceptions" breakpoint from Xcode and instead:
Add a Symbolic Breakpoint on objc_exception_throw
Set a Condition on the Breakpoint to (BOOL)(! (BOOL)[[(NSException *)$x0 className] hasPrefix:#"_NSCoreData"])
The configured breakpoint should look something like this:
This will ignore any private Core Data exceptions (as determined by the class name being prefixed by _NSCoreData) that are used for control flow. Note that the appropriate register is going to be dependent on the target device / simulator that you are running in. Take a look at this table for reference.
Note that this technique can be adapted easily to other conditionals. The tricky part was in crafting the BOOL and NSException casts to get lldb happy with the condition.
I wrote an lldb script that lets you selectively ignore Objective-C exceptions with a much simpler syntax, and it handles both OS X, iOS Simulator, and both 32bit and 64bit ARM.
Installation
Put this script in ~/Library/lldb/ignore_specified_objc_exceptions.py or somewhere useful.
import lldb
import re
import shlex
# This script allows Xcode to selectively ignore Obj-C exceptions
# based on any selector on the NSException instance
def getRegister(target):
if target.triple.startswith('x86_64'):
return "rdi"
elif target.triple.startswith('i386'):
return "eax"
elif target.triple.startswith('arm64'):
return "x0"
else:
return "r0"
def callMethodOnException(frame, register, method):
return frame.EvaluateExpression("(NSString *)[(NSException *)${0} {1}]".format(register, method)).GetObjectDescription()
def filterException(debugger, user_input, result, unused):
target = debugger.GetSelectedTarget()
frame = target.GetProcess().GetSelectedThread().GetFrameAtIndex(0)
if frame.symbol.name != 'objc_exception_throw':
# We can't handle anything except objc_exception_throw
return None
filters = shlex.split(user_input)
register = getRegister(target)
for filter in filters:
method, regexp_str = filter.split(":", 1)
value = callMethodOnException(frame, register, method)
if value is None:
output = "Unable to grab exception from register {0} with method {1}; skipping...".format(register, method)
result.PutCString(output)
result.flush()
continue
regexp = re.compile(regexp_str)
if regexp.match(value):
output = "Skipping exception because exception's {0} ({1}) matches {2}".format(method, value, regexp_str)
result.PutCString(output)
result.flush()
# If we tell the debugger to continue before this script finishes,
# Xcode gets into a weird state where it won't refuse to quit LLDB,
# so we set async so the script terminates and hands control back to Xcode
debugger.SetAsync(True)
debugger.HandleCommand("continue")
return None
return None
def __lldb_init_module(debugger, unused):
debugger.HandleCommand('command script add --function ignore_specified_objc_exceptions.filterException ignore_specified_objc_exceptions')
Add the following to ~/.lldbinit:
command script import ~/Library/lldb/ignore_specified_objc_exceptions.py
replacing ~/Library/lldb/ignore_specified_objc_exceptions.py with the correct path if you saved it somewhere else.
Usage
In Xcode, add a breakpoint to catch all Objective-C exceptions
Edit the breakpoint and add a Debugger Command with the following command:
ignore_specified_objc_exceptions name:NSAccessibilityException className:NSSomeException
This will ignore exceptions where NSException -name matches NSAccessibilityException OR -className matches NSSomeException
It should look something like this:
In your case, you would use ignore_specified_objc_exceptions className:_NSCoreData
See http://chen.do/blog/2013/09/30/selectively-ignoring-objective-c-exceptions-in-xcode/ for the script and more details.
Here is an alternative quick answer for when you have a block of code e.g. a 3rd part library that throws multiple exceptions that you want to ignore:
Set two breakpoints, one before and one after the exception throwing block of code you want to ignore.
Run the program, until it stops at an exception, and type 'breakpoint list' into the debugger console, and find the number of the 'all exceptions' break point, it should look like this:
2: names = {'objc_exception_throw', '__cxa_throw'}, locations = 2
Options: disabled
2.1: where = libobjc.A.dylibobjc_exception_throw, address = 0x00007fff8f8da6b3, unresolved, hit count = 0
2.2: where = libc++abi.dylib__cxa_throw, address = 0x00007fff8d19fab7, unresolved, hit count = 0
This means it is breakpoint 2. Now in xcode, edit the first breakpoint (before the exception throwing code) and change the action to 'debugger command' and type in 'breakpoint disable 2' (and set 'automatically continue...' checkbox ).
Do the same for the break point after the offending line and have the command 'breakpoint enable 2'.
The all breakpoints exception will now turn on and off so it's only active when you need it.
